Advanced Tab
Advanced Tab provides some useful image enhancement tools for you to
precisely tailor the image before the final scan. The effects of changes you
make are shown in the
Preview Window
immediately.
There are 4 tabs at the lower section of Advanced Tab: Gamma, Histogram,
HSL and Threshold.
These items are intended for users who are familiar with
image editing tools and how they affect images.
If you are just learning how to
scan, then we strongly recommend not using these features until you become
familiar with your scanner and its terminology.
Many image-editing programs
already have these features.
However, if the need arises to adjust the color
level of your scanned images, then click on the appropriate tab and perform the
adjustments. Note: Before adjusting the Gamma, Histogram and/or HSL,
perform a
PREVIEW
so you can view the changes before you scan.
